  • the plastic housing has proven in prolonged use in practice as not sufficiently sustainable dimensional stability, especially in the aforementioned induction cooktops, where due to the large weight of the copper coil radiator and due to thermal influence after prolonged use of the plastic tends to deformation and leads to an undesirable change in the trough geometry, especially when the housing of the cooktop carries switching elements, eg so-called
  • the present invention has for its object to form a cooktop of the type mentioned in particular with induction radiators and so-called stoves so that with simple technical means, an undesirable change in the cooktop geometry even after a long period of operation is not to be feared.
  • Base can be considered in particular the housing of a stove eg a so-called stander, on the open top of the hob is placed and connected to the upper edges of the housing, but also eg a worktop in the cut the cooktop is used or a cooktop forming glass ceramic plate to form a structural unit with the radiator modules ,

  • a connecting element may, as stated above, be formed in the form of a shield plate.
  • the at least one support rail between end-side fastening elements has a substantially U-shaped profile, wherein the free legs of the profile may have multiple cuts. In this way, stability and dimensional stability of the mounting rails is ensured even under heavy load and by the incisions mentioned an uneven surface structure of the housing bottom is followed or it will be the eg for purposes cooling air flowing from the bottom of the housing is not prevented from passing through.
  • a further preferred embodiment of the cooktop according to the invention is provided in that the housing is connected at several attachment points with a cooking surface forming a preferably glass-ceramic well plate and that the at least one support rail at least at the base, preferably at the upper edges of a housing connected to the radiator module, e.g. a stander, is attached.
  • the top of e.g. shell-like housing stably fixed and serving as a carrier for the heavy radiator modules trough bottom is securely held by the at least one support rail in a predetermined shape.

Ultimately, you need less to install parts for mounting the hob, which can also reduce the cost of production.
